JENSIgame Video System

                  (a 37-pin AMP plug standard pinout)

This is a pinout standard that was developed by JENSIgame in the 
1970s and seems to have been popular among operators in Sweden. 
According to the inventor, one advantage with this standard is 
that the pins in the connector can handle up to 7 Ampere, when 
pins in other connectors usually have a limit of about 3 Ampere.

This text might be of help if you for example need to convert a 
game which has been rewired according to the JENSIgame system.
